A Harned [Har-ned] Cell is a device used for measuring this quantity, and other devices used to measure this quantity have an asymmtetry potential that arises due to the presence of an electrode. The attachment of a certain ion to a central nitrogen atom creates a positive charge on its adjacent nitrogen, which eventually leads to a distinctive change allowing its quantification. This quantity is related to the pKa according to the Henderson-Hasselbalch equation, and buffers minimize changes in this quantity for a system. For 10 points, identify this quantity that is equal to the negative log base 10 of the hydrogen ion activity, which for wa
